have you checked dsPICs and PIC24 as well?

Though I'd find it strange that, @9600 baud, you did employ the whole 
power of PIC (what clock speed, by the way?) , I can tell that you could 
use one (or 2) SPI-slave device which act as USART. Somebody 
(JBroadwell?) at forum.microchip.com did do that.
